1/2 Beginning inventory



4/19 Purchase



6/7 Purchase



12/16 Purchase




Woods and Moon were sold during the year for a total of $35,000. Determine the firm’s

a. cost of goods sold.

b. gross profit.

c. ending inventory.

2. Inventory valuation methods: basic computations. The January beginning inven­tory of the White Company consisted of 300 units costing $40 each. During the first quarter, purchases were:

Date                     Quantity              Cost

1/15                      700                       $45

1/31                      1200                     $48

2/12                      800                       $46

2/27                      650                       $51


Sales during the first quarter were.

Date                     Sold

1/19                      500

2/2                        600

2/13                      500

2/28                      100

Perpetual inventory system: journal entries. At the beginning of 20X3, Beehler Company implemented a computerized perpetual inventory system. The following transactions occurred:


Purchases on account: 500 units @
$4 =  $2,000

·        Sales on account: 300 units @ $5 = $1,500

·        Purchases on account: 600 units @
$5 =  $3,000

·        Sales on account: 300 units @ $5 = $1,500

a. Prepare journal entries for the above purchases and sales.

b. Calculate the balance in the firm’s Inventory account.


Inventory valuation methods: computations and concepts. Wave Riders Surfboard Company began business on January 1 of the current year. Below are the transactions for the year






Purchase 100 boards  @ $125


Sold 50 boards @ $250


Purchase 200 boards  @ $135


Sold 75 boards @ $250


Purchase 100 boards  @ $145

Purchase 100 boards  @ $155

Sold 300 boards @ $250

Purchase 100 boards  @ $140


Wave Riders uses a perpetual inventory system.



a. Calculate cost of goods sold, ending inventory, and gross profit under each of the following inventory valuation methods:


First-in, first-out

·               Last-in, first-out

·               Weighted average


b. Which of the three methods would be chosen if management’s goal is to

(1) produce an up-to-date inventory valuation on the balance sheet?

(2) approximate the physical flow of a sand and gravel dealer?


5. Depreciation methods. Betsy Ross Enterprises purchased a delivery van for $30,000 in January 20X7. The van was estimated to have a service life of 5 years and a resid­ual value of $6,000. The company is planning to drive the van 20,000 miles annually. Compute depreciation expense for 20X8 by using each of the following methods:

a. Units-of-output, assuming 17,000 miles were driven during 20X8

b. Straight-line

c. Double-declining-balance

6. Depreciation computations. Alpha Alpha Alpha, a college fraternity, purchased a new heavy-duty washing machine on January 1, 20X3. The machine, which cost $1,000, had an estimated residual value of $100 and an estimated service life of 4 years (1,800 washing cycles). Calculate the following:

a. The machine’s book value on December 31, 20X5, assuming use of the straight-line depreciation method

b. Depreciation expense for 20X4, assuming use of the units-of-output depreciation method. Actual washing cycles in 20X4 totaled 500.

c. Accumulated depreciation on December 31, 20X5, assuming use of the double-declining-balance depreciation method.


7. Depreciation computations: change in estimate. Aussie Imports purchased a specialized piece of machinery for $50,000 on January 1, 20X3. At the time of acquisition, the machine was estimated to have a service life of 5 years (25,000 operating hours) and a residual value of $5,000. During the 5 years of operations (20X3 – 20X7), the machine was used for 5,100, 4,800, 3,200, 6,000, and 5,900 hours, respectively.


a. Compute depreciation for 20X3 – 20X7 by using the following methods: straight line, units of output, and double-declining-balance.

b. On January 1, 20X5, management shortened the remaining service life of the machine to 20 months. Assuming use of the straight-line method, compute the company’s depreciation expense for 20X5.

c. Briefly describe what you would have done differently in part (a) if Aussie Imports had paid $47,800 for the machinery rather than $50,000 In addition, assume that the company incurred $800 of freight charges $1,400 for machine setup and testing, and $300 for insurance during the first year of use.
